HEBER SPRINGS, Ark. - Authorities say they found country singer Mindy McCready's body on the same porch of her northern Arkansas home where her boyfriend was found dead of an apparent suicide last month.

Cleburne County Sheriff Marty Moss said Monday that it appears McCready killed her late boyfriend David Wilson's dog before she turned the gun on herself Sunday.

The dog and McCready were found dead next to one another the home in Heber Springs, a vacation community about 65 miles north of Little Rock. Moss says the dog's body was next to McCready's.

Authorities are investigating Wilson's shooting death as a suicide, but Moss says an official determination hasn't been made.

Moss says he expects McCready's official cause of death to be released soon, but that "all indicators" point to suicide.
